Abstract The global energy crisis and environmental concerns are driving research into renewable sustainable conversion storage technologies. Solar energy, as an ideal resource, has significant potential to contribute the goal of net‐zero carbon emissions if effectively harnessed converted a reliable storable form energy. Photocatalysts have convert sunlight chemical carriers. In this respect, covalent organic frameworks (COFs) shown great promise due their tunable structure on different length scales, high surface areas, beneficial optical properties such broad visible light absorption. This review offers comprehensive overview key developments in COF‐based photocatalysts for various applications, including water splitting, hydrogen peroxide generation, transformations, dioxide nitrogen reduction. underlying mechanisms, essential principles material design, structure‐function relationships COFs photocatalytic applications discussed. challenges faced by also summarized strategies enhance performance explained, improving crystallinity, regulating molecular structures, tailoring linkages, incorporating cocatalysts. Finally, critical proposed utilization photocatalytically generated chemicals value‐added products.

Photocatalytic technology is an attractive option for environmental remediation because of its green and sustainable nature. However, the inefficient utilization solar energy powder morphology currently impede practical application. Here, we designed a floatable photocatalyst by anchoring 0D Cu2(OH)PO4 (CHP) nanoparticles on 2D graphene to construct 0D/2D CHP/reduced oxide (rGO) aerogels. The CHP/rGO aerogels have interconnected mesopores that provide large surface area, promoting particle dispersion increasing number active sites. Moreover, optical response aerogel has been significantly expanded cover full spectrum light. Notably, 20%CHP/rGO displayed high degradation rate (k = 0.178 min–1) taking methylene blue (MB) as model pollutant under light irradiation (λ > 420 nm). enhanced photocatalytic activity ascribed rapid electron transfer in heterostructures, supported DFT theoretical calculations. Our research highlights responsive photocatalysts elimination organic pollutants from wastewater irradiation, well potential catalyst recovery using meet industrial requirements.
